Question by drex150 · Mar 20, 2015 at 06:46 AM · transform.forward

Transform.forward is constantly changing when it shouldn't.

So I set up a script that sets the transform.forward of my player to be the same as my camera. This allows me to move the camera around but the player's controls will always work with the camera. Basically, holding up is always moving away from the camera no matter what direction the camera is facing.

The whole thing worked great. I thought I had it figured out. Then I collided with a wall. When the player collides with a wall at an angle, basically anything other than directly straight on, when I let go of my controls the player's transform.forward spins. It eventually slows down and stops. All of this shouldn't be happening because I only am setting the player's transform.forward when the left joystick is actually in use. So if you don't hold a direction, he shouldn't change his transform.forward...but he is anyway.

 if(Input.GetAxis("Horizontal") >= 0.1f || Input.GetAxis("Horizontal") <= -0.1f || Input.GetAxis("Vertical") >= 0.1f || Input.GetAxis("Vertical") <= -0.1f)
 {
     transform.forward = new Vector3 (playerCam.transform.forward.x, 0, playerCam.transform.forward.z);
 }

I have checked that it is the player's transform forward only, the camera does not change. I also checked if the controls maybe weren't getting between 0.1 and -0.1. They are getting 0 when this happens. This only happens when the joystick is between those numbers. In other words, it's happening when it actually shouldn't be. There are no other lines that modify transform.forward.

How are you moving the player? By adding force? Animation?

I tried with force, then transform, then velocity, the same thing happens regardless of how the player is moved. I even moved him manually with the editor and as soon as he collided with the wall, he started rotating his forward.

I've also tried changing the object that it takes on the forward of, no difference, still was spinning even though the object was static and never moved.

What I'm thinking is that if your character is a cylinder (as most are), and you're moving into a wall at an angle, that will cause the character to roll along the wall, causing "spinning". That might be what you're facing.

You should probably try placing your character inside an empty gameobject for starters, and refer to the empty gameobject's transform when moving.

@Baste Lol, wow, so what you said gave me an idea. I didn't have the Y rotation constrained in the rigidbody. Turned it on and the spinning stopped but I can still rotate and everything. So I guess it was building up some rotation by sliding against the wall, but since holding a direction forced the character not to rotate I didn't see it until I stopped holding a direction. I guess it build up some torque or something that didn't go away even though the character wasn't spinning until I stopped moving.

Anyway, you basically got the answer, thanks for the help.
